XENON at Gran Sasso in Italy

The XENON100 is one of the largest experiments in operation for direct dark matter detection. It is the international collaboration, consisting of 90 researchers. The current phase of 100 kg experiment (XENON100) has produced the world best limit so far. The next generation 1 ton experiment (XENON1T) began construction in 2012.



XENON100 is a double phase liquid xenon detector, consisting of 162 kg of xenon (with ~50 kg fiducial mass), viewed by ~250 1 inch square PMT. It stated stable operation in later 2009, and has been taking the data for 3 years. UCLA group has contributed to its construction, commissioning, operation and data taking. Three students have completed their PhD (Ethan Brown, Chi Wai Lam, Artin Teymourian).



Based on the successful operation of the XENON100, the coloration began construction of XENON 1Ton detector in 2012. As shown above, it will be installed inside of 10 m size water tank. The total mass of xenon is 2.5 ton and the fiducial mass will be 1 ton. With such a large mass, we expect to achieve 100 times better sensitivity than XENON100, enough to cover the phase space of SUSY predictions.
